Detailed studies are made as follows: Searching the key internal factors which can affects slope stability. According to the geological data which was gained by exploration investigation, establishing a geological model which can reflect rock mass characteristics;With analyzing the internal and exterior factors synthetically, the deformation and possible failure mechanism and mode of the cut slopes was confirmed which combines with stereoic projection and other techniques;The stabilities of the 14 high slopes are estimated synthetically by applicable design codes and guidelines. With the estimate result and some other analysis methods, the rock mass mechanical parameters of slope are identified;As a results, 14 high slopes fall into 4 categories based on rockmass characteristics and discontinuities. The stability and deformation of some typical slopes was analyzed with distinct element method by UDEC;The safety factor of some dangerous slopes are calculated by rigid limiting equilibrium method for coMParison.

首先着重研究影响边坡稳定性的内在因素，主要是通过地质勘探、测量、现场观测等手段取得研究区地质体的基础地质资料，建立起能够反映地质体结构特征的地质模型；随后综合分析潜在的内外部影响因素，并结合赤平投影对边坡可能的失稳模式或破坏机制作出判断；运用已有岩体质量分类方法对沿线14个高陡边坡稳定性进行初步的评价，并结合试验研究、经验判断、工程类比等手段确定了坡体的岩体力学参数；根据稳定性初步评价结果将研究区14个高陡边坡按开挖方式分为4大类，并利用离散元程序UDEC对各类典型高陡边坡进行了稳定性计算分析；对潜在危险边坡利用刚体极限平衡法求出了不同工况下的安全系数。

ACTH〓 at concentration of 10〓-10〓 had no significant influence on the saturation curve, Scatchard plot and Hill plot of 〓-DAGO binding to rat brain membrane.

〓在〓范围内对〓的饱和曲线，Scatchard图形及Hi11图形没有明显的影响；但在较高浓度时可以完全取代〓与其受体的结合，〓为37.1±21.8μmol/L，其抑制μ配体〓结合的强度与δ受体的配体DPDPE和κ受体的配体U50488H大致相当，只是稍弱一些，分别是它们的1／8和1／4。

From the equilibra configures obtained during simulating, it was suggested that there is mainly chaintype structure in the LiBO〓 melt, and the dominative variations during the process of being fused may be the decomposition of the long chains, then large member of nonbridge oxygen was come into being in the shorter chains resulting from the decommission.

模拟得到的二硼酸锂熔体中，三配位和四配位的硼氧结构共存，其间相互结合成环状结构；而在偏硼酸锂熔体中没有发现四配位构型，由平衡构像分析，该熔体中可能以链式结构为主，熔化过程中主要的结构变化是长链的分解，分解产生的短链结构产生了大量非桥氧。
